During construction of the new bed, this separation was not maintained by the contractor. During inspections with MOA this separation violation was discussed. We discussed the options resulting in this request to reduce separation from 10 -feet down to 6 -feet at the closest point. The separation can be viewed on the Plan drawing. It is not likely that any adverse conditions will result from this proximity. The two shallow beds are both 2 -feet below original grade. Stability of soil is not a factor. The overall grade in the area is under 5%. The hydraulic loading of the new bed will transfer vertically downward through native sandy soil. The proximity of the former bed/alternate site will not interfere with effluent flow. We request approval of the 6 -foot separation between new absorption bed and alternate field.

Box 196650 Anchorage, AK 99519 Re: Armstrong -Johnson, Lot 2 Narrative & Permit Application Dear Mr. Cross: The proposed septic system will have very limited impact on adjacent properties for the following reasons: 1. The surrounding lots are large, allowing sufficient room for septic sites. 2. Immediate neighboring septic systems are all +30' distance. 3. Reserve space is adequate, due to absorption capacity and community water system. 4. Drainage will not be affected and is not a major consideration in our design. If you have any questions please call our office at 694-5195. Sincerely, Louis Butera, P.E. \1996\NARRAT-2.Doc SPECIFICATIONS FOR ON-SITE SEPTIC SYSTEM LEGAL: Armstrong -Johnson Lot 2 A. GENERAL 1. The septic plan is for a single family residence only. 2. The drawing and or site plan shall be a part of this specification. 3. All materials and workmanship shall meet the Anchorage Department of Health requirements. 4. All soil tests are advisory to the design and are to be verified or modified in the field by the engineer. 5. All excavations and depths are advisory and are to be verified in the field by the contractor to meet Municipality of Anchorage requirements. 6. It is the responsibility of the owner to obtain all necessary permits or easements and to locate any adjacent multi -family wells. 7. The excavation is to be exactly in the area shown on the site plan, any deviation requires engineer approval. 8. It is always recommended that a surveyor locate the nearest lot line position and the location of any easements. 9. Any remaining open test hole excavations shall be filled. B. SEPTIC TANK/LIFT STATION 1. Septic tank and lift station shall be 1,500 gallon Orenco/Anchorage Tank model OSI 05-20-HHF. 2. Receipt from licensed electrician stating the lift station was wired to applicable codes to be supplied to Engineer. C. BED 1. The bed excavation is to follow the natural land contour to maintain a maximum total depth of the bed bottom of 2'. 2. The bottom of the bed shall then be leveled with pit run sand material < 5 % silt to plus or minus 1.5", as needed. 3. A F gravel bed is to be placed with pressure laterials buried with 2" of gravel over pipe. 4. The effluent line within the bed shall be laid with 1/8" holes in pressure effluent line shall be oriented up with orifice shields in place, holes spaced at 32" OC. 5.

TEST: PASSED XXX FAILED COMMENTS: This system appears to be operating satisfactorily, though the SAS is approaching the end of its useful life. There was no measurable liquid in the SAS MTs prior to beginning the test. Test flow needed to be added to the system over an extended timeframe to keep the liquid level depth from exceeding the ED of the SAS. A recovery measurement, taken 20 minutes after stopping the test flow, showed satisfactory absorption with nearly a return to the starting level. Test flow volume exceeded the design daily now. fhb Reviewed by: Paul Pinard Date: 3/4/13 /Gsyz 'r2 i, ti •~ aGwXttL a A0-'JvulA-utb 1AND JUEVEY1NG b94-0829 I HEREBY CERTIFY THAT I HAVE SURVEYED THE SCALE: FOLLOWING DESCRIBED PROPERTY: � Q ��4Q� .9.�/Jis7.?or/G-.7a/,�•Yso�!/fl/B for Zr`Q�''��S' b DATE: AND THAT NO ENCROACHMENTS EXIST EXCEPT AS j r�e�fllf INDICATED.
